Subquantum Detection Theory -sdt

We show that the cornerstone of QM – Born's rule – can be obtained from detection theory (SDT) for subquantum (classical) random field. The basic assumption of SDT is that the probability of detection of a field (=signal) is proportional to the power of this field (its L 2-norm). Our approach has some similarities with the semi-classical approach to the electromagnetic field. However, formalisms describing random fields are different. Moreover, our approach is applicable to any kind of field, e.g., electronic or neutronic field. But the crucial difference is that SDT provides a possibility to go beyond QM. We extend SDT by modelling measurements with the aid of detectors which are sensitive to nonquadratic influence of the subquantum random field. Difference between probabilistic predictions of QM and SDT is estimated.
